OILING DEVICE FOR JOURNAL BOXES.

Application ledFebruary 7, 1924-..k Serial No. 691,151. i

To all 'whom t may concern:

Be it known that I, CHARLns B. ROYAL, a citizen of the United States,residing at Chicago, in the ,county of Cook and State 5 of Illinois,have invented a new and useful Improvement inOiling Devices for JournalBoxes, of which the following is a specification. Y

This invention lrelates to means for lul bricating journal boxessuch asare used on' trucks of railway cars and the like.

The space beneath theV journal and with-` in the journal box is commonlyfilled with waste and oil is poured over this. This l oil is carried ytothe journal by capillary attraction. "For many reasons this method ofoiling the journal is very unsatisfactory.

The primary object of this invention is oil from the pocket in thebottom of the journal box to the journal as the latter rotates.

This and other objects are accomplished by this invention which is fullydescribed in the following' specification and shown in the accompanyingdrawings in which:

Figure 1 is a longitudinal section through the journal box on the line1-1 of Fig.,2;

Fig. 2 is a transverse section on the line 2-2 of Fig. 1; and

Fig. 3 is a partial developed view of the` flexible oiling member.

The invent-ion is applied to a standard journal box having a housing 10,such as is commonly used on the trucks of railway cars and the like. Thehousing 10 surrounds the journal 11 on the endof the shaft 12, thejournal supporting suitable bearing members 13 and 14 such as arecommonly employed for this purpose.

The lower part of the housing 10 has a bottom 15 providing a pocket 16beneath the journalfll. Within the space I have provided an oilingdevice comprising a flexible member made up of a seriesof felt strips 17secure-d in any suitable manner as by stitching to an endless belt 18which may be made of any suitable material such as cotton fabric.

Thisiexiblc member passes over two rollers 19 and 20 which arejournalledvupon pins 21 and 22 which in turn'are carried by crossed bars23 and 24 which are pivotally connected near their center, thelower Aendbearing upon theihousing bottom 15.

to provide a suitable means for conveying' AiS as follows:

These bars are connected by pins 25 .and 26 upon which is mounted aroller 27 which has a grooved or spiked surface 28, the latter bearingupon the inner surface of the flexible-member at ,the bot-tom of itsswing. An operating lever 29 is connected tothe pin 25..

A tension spring 30 at each rend of the bearing connects the bars 23 and24 'and serves to force the rollers 19 and 2O toward each other therebypressing the felt strips 17 into contact with the journal.

In addition to the action already described, cil is fed to the journalby the flexible member which acts as a wick, conveying oil by capillaryattraction from the y body of oil in the bottom of the journal box.

The method of operation of the device As the axle turns there is a smallamount of friction betweenthe journal 11 and felt strips 17 which causesthe flexible member to gradually move in the direction of the surface ofthev journal with which it is in contact, but at a very much slower rateof speed. As this occurs the felt strips 17 pick up oil from the'kbottom of the journal box and carry it around into Contact with thejournal, thereby thoroughly lubricating the same. In case, how` everitis desired that oil shall be quickly fed to the bearing, particularlywhen the bearing has remained stationary for a long period of time,the'operator raises the housing cover 10a and reaches in through thefront opening, moves the lever 29, thereby causing the flexible memberto be moved. thus bringing a fresh supply of oil into contact with thejournal.

While I have shown and described certain embodiments of my invention,itis to be understood that it v1s capable of many modifications. Changestherefore in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims, in which it is my intention to claim all noveltyinherent in my in-L vention as `b-roadly as possible in view of theprior art.

I claimz' .1. In a railway journal box, in combination, a journal havingbearing upon its upper surface, a bearing housing surrounding saidjournal and having an oil pocket beneath the same, a flexible memberadapt ed to dip -into said oil and to have frictional engagement Withsaid journal to Cause said flexible member to move to carry oil to saidjournal, said flexible member oomprising a series of parallel strips offelt Secured to an endless fabric belt.

2; In a railway journal box, in combination, a journal having bearingupon its upper surface, a bearing housing surrounding said journal andhaving an oil pocket beneath the same, a flexible member adapted to dipinto said oil and to have frictional engagement with said journal tocause said flexible'member to move to carry oil to said journal, saidflexible member comprising a series of parallel strips of felt securedto an endless fabric belt, and meansv for mov ing said flexible memberindependently of the movement of the journal.

3. In a railway journal box, in combination, a journal having bearingupon its upper surface, a. bearing housing surrounding said journal andhaving an oil pocket beneath the same, a flexible member adapted to dipinto said oil and to have friotional engagement with said journal tocause said flexible member to move to carry oil to said journal, saidflexible member comprising` a series of parallel strips of felt securedto an endless fabric belt, and a sprocket engaging said flexible memberfor independently moving said member.
